Abstract
Description
- The present invention relates to a gas lighter.
- In general, many small parts are assembled into a gas lighter.
- As for a gas lighter of the type which uses a fire-striking unit with a rotatable file adapted to rotate in a horizontal plane, the gas ejection nozzle is located apart from the flame opening, and therefore a pipe is used to connect the ejection nozzle to the flame opening. The pipe is a separate, independent part, requiring one extra assembling step. The work of building a pipe into the assembled structure requires skillfulness. For these reasons the building-in of this small part in the gas lighter structure is one cause for making it difficult to perform assembling work continuously with an increased efficiency.
- In view of this one object of the present invention is to provide an improved gas lighter of the type which uses a fire-striking unit with a rotatable file adapted to rotate in a horizontal plane, permitting necessary assmebling work to be continuously efficiently performed by reducing the number of parts to be manually built in, and accordingly simplifying the assembling line.
- To attain the object of the present invention a gas lighter of the type which comprises a main body having a gas well, a gas-ejection nozzle fixed to the ceiling of the gas well, and a cap operatively connected to the gas-ejection nozzle; and a fire-striking unit fixed to the top of the main body and having a rotatable file adapted to rotate in a horizontal plane, is improved according to the present invention in that the fire-striking unit has a pipe under its bottom surface, the pipe communicating with the gas-ejection nozzle at its rear end and being open at its top end in the vicinity of the rotatable file.
- With this arrangement the pipe will be automatically put in connection to the gas-ejection nozzle simply by fitting the fire-striking unit in the top space of the main body.
- Other objects and advantages of the present invention will be understood from the following description of a gas lighter according to one embodiment of the present invention, which is shown in the accompanying drawings:
- Fig. 1 is an exploded longitudinal section of a lighter according to one embodiment of the present invention;
- Fig. 2 is an exploded side view of the gas lighter; and
- Fig. 3 is a perspective exploded view of the gas lighter.
- In the drawings "A" indicates a gas lighter of the type which comprises a main body 1, a fire-
striking unit 2 having arotatable file 10a adapted to rotate in a horizontal plane and acap 3. The main body is made of plastics, and has a gas well 4. A gas-ejection nozzle 5 is fixed to the ceiling of the gas well, and thecap 3 operatively connected to the gas-ejection nozzle 5. The fire-striking unit 2 is fixed to the top of the main body 1. - The main body 1 has a
bottom closure 4a. Atop closure 6 has an opening in alignment with the opening 4b of the ceiling of the gas well 4, and the lower part of thegas ejection nozzle 5 is inserted in these aligned openings. The gas-ejection nozzle 5 is composed of an outerhollow cylinder 6a threadedly engaged with thetop closure 6, a gas-ejection pipe 6b vertically movably fitted in the outerhollow cylinder 6a with its tip end projecting from the upper surface of the outerhollow cylinder 6a, and an innerhollow cylinder 6c inserted at its top end in the bottom of the outerhollow cylinder 6a and at its bottom end in the opening 4b of the ceiling of the gas well 4. - The gas-
ejection pipe 6b is biased by a spring S1 down to the lower position in which itsmovable rubber 7 closes theaperture 6d of the innerhollow cylinder 6c. - An
operating lever 8 is fixed to the tip end of the gas-ejection pipe 6b via a rubber ring G. Theoperating lever 8 hasopposite pivot projections 8a at its front end, andopposite catch extensions 8b at its rear end. - The fire-
striking unit 2 is composed of aholder 9, a fire-striking mechanism 10 and aconnecting pipe assembly 11. Theholder 9 is made of plastics, and has a "U"-shaped section withcatch hooks 9a integrally connected to its bottom corners. Theholder 9 can be fixed to the main body 1 with itscatch hooks 9a caught by thecatch slots 9b of thetop closure 6. - As shown, the
holder 9 hasopposite reentrances 9c made at its lower front, and when the fire-striking unit 2 is fixed to the main body 1, theopposite pivot projections 8a of theoperating lever 8 are snugly accommodated in thesereentrances 9c of theholder 9, thereby permitting theoperating lever 8 to rotate a little about itspivot 8a for raising the gas-ejection pipe 6b when thecap 3 is opened. - An
inner cap 12 is made of metal, and it has a flame opening 12a and aconnection pipe assembly 11 fixed to its lower surface. - The connecting
pipe assembly 11 is composed of an "L"-shaped pipe 11b and an "L"-shaped connector 11a. The "L"shaped connector 11a has a throughchannel 11c opening at its opposite ends. Thepipe 11b is inserted into the upper outlet of the channel with its one leg upright. Theconnector 11a is fixed to the lower surface of the bottom of the fire-striking unit 2. Thus, when theholder 9 is fixed to the main body 1, theconnector 11a will be set on the gas-ejection pipe 6b. Then, it is fitted in the lower inlet of thechannel 11c of theconnector 11a. At the same time, the free end of thepipe 11b is put in the vicinity of the fire-striking unit 10. This particular way of fixing a pipe to the underside of the fire-striking unit in the holder should not be understood as being limitative. It is important that the pipe is fixed to the underside of the fire-striking unit in holder in right position, no matter how the pipe is fixed to the underside of the fire-striking unit. The pipe can be fixed to the fire-striking unit in different ways. - The fire-
striking machanism 10 comprises arotatable file 10a and aflint 10b. Thefile 10a is located adjacent to the flame opening 12a, and is adapted to rotate in a horizontal plane. Theflint 10b is pushed against the file by spring S2. - The
rotatable file 10a is connected coaxially to arotary cylinder 13, which is to be rotatably fixed to the main body 1. When therotary cylinder 13 is rotated, the gas ejected from the connectingpipe 11 is ignited. - The fire-
striking unit 2 can be intergrally combined with the main body 1 by pushing and fitting the fire-striking unit 2 in the main body 1 to permit thecatch hooks 9a of theholder 9 to be caught by thecatch slots 9b of thetop closure 6, and then therotary cylinder 13 is put on the shoulder of the main body 1 with itsprojection 13a inserted in the center counter hole of therotary cylinder 13. - When the fire-
striking unit 2 is integrally combined with the main body 1, the connectingpipe 11 is put in connection to the gas-ejection nozzle 5. - The
cap 3 comprises ametal enclosure 3a to cover the fire-striking unit 2, and asupport piece 3b, which is inserted into the rear slot of themetal encloure 3a. Thesupport piece 3b haspivots 3c projecting from its opposite sides. Thesepivots 3c are inserted in theholes 14a which are made on the opposite rearupper extentions 14 of the main body 1. Thus, thecap 3 is rotatably fixed to the main body 1 with itssupport piece 3b abutting on a lock 15 and a spring-biased push pin 15a. Thecap 3 can be rotated about itspivot 3c between opening and closing positions. - As shown the
support piece 3b has a recessed portion 3d. Therear extension 8b of theoperating lever 8 is caught by the recessed portion 3d of the support piece, and therefore theoperating lever 8 is rotated to raise the gas-ejection pipe 6b for ejection of gas when thecap 3 is opened. - As may be understood from the above, the building-in of the connecting pipe on the lower surface of the bottom of the fire-striking unit permits reduction of the number of parts to be manually handled in the assembled line, and accordingly simplifying the asembling work and increasing the efficiency with which necessary parts are assembled.
- This contributes to the increase of continuity in the automatic assembling work by eliminating the necessity of manualy handling a selected part, and accordingly reduction of manufacturing cost.
